A few things we’re great at

Tax Planning

Generally speaking, tax planning is defined as analyzing a client’s past and current finances, review of prior tax returns and discussion of future goals with a tax attorney to ensure that all available advantages contained within the Internal Revenue Code are utilized to minimize tax exposure.

Tax Audit Defense

Tax Defense

Few things in life are more intimidating than facing a tax audit examination. A tax audit is the examination of an individual or business return to verify that all items reported are accurate and substantiated. Our tax practice focuses primarily on audit representation (in field, mail, or office audits) for individuals and small businesses, both on domestic issues and international/treaty positions.

Tax Litigation

Tax Planning

A tax controversy commences at the administrative (agency) level and generally arises from a tax audit (also known as a tax examination) or taxes owed from a filed/amended return. Our tax attorneys represent individual and corporate clients to resolve their tax controversy at all levels, including administrative, appeals, and, if necessary, US Tax Court or Oregon Tax Court. As an alternative to the time, cost, and expense of a trial, we can also assist with alternative dispute resolution, including Fast Track Mediation and/or arbitrating settlements with the IRS/Oregon Department of Revenue.

Estate Planning & Administration

Estate Planning

An estate plan puts you in control of end-of-life decisions. Essential for adults of all ages, it provides for your loves ones and ensures that your property is distributed according to your wishes. It’s also a crucial component of your overall financial plan, and can help your heirs avoid paying substantial taxes and fees.

Business & Corporate Law

There is no question that experience matters. At Hagen O’Connell & Hval, we are more than good lawyers: we are industry professionals. We strive to understand our clients’ businesses inside and out. Our clients are diverse, ranging from startups and emerging enterprises to family-owned and privately held companies and multinational, publicly traded corporations.

We have an extensive practice in Merger and Acquisition of businesses. We have handled many mergers and acquisitions in almost every type of business. We work with the clients in preparing the business for sale thru closings.

Real Estate Law

Our real estate law practice focuses on helping individuals and families efficiently resolve common challenges involving real property, including the purchase and sale of real estate, preparation and review of lease agreements whether residential or commercial, boundary disputes, deeds, and more.

We officially closed the sale today. Thank you for all your help getting us to this point! You brought so much peace of mind and I really appreciate how responsive you are. I can’t imagine doing something like this without you on my side.

Hopefully I’ll talk them into purchasing the next venture too and we can work together again on that one! But in the meantime if I ever have any legal questions or need help I’ll reach out to you first

I can’t express the real meaning to me this is. I know the hard work you have done and have put up more than effort here. Thank you for your perseverance and understanding representing me. It’s more than the money it’s about doing the right thing. And you have made that a whole new meaning to me.
